All Leupold VX-6 riflescopes are CDS® capable and include one free Custom Ballistic Dial with purchchase. Leupold Argon/Krypton second generation waterproofing resists the effects of thermal shock much more efficiently than standard nitrogen.

CDS (Custom Dial System)

Leupold CDS™ models allow you to quickly dial your elevation to different sight-in ranges with a custom adjustment matched to your specific ballistics information. The CDS dials change out easily, allowing you flexibility with different loads, conditions and calibers.Every CDS dial features ¼-MOA click increment finger adjustments and no adjustment covers to lose, making the VX-2, VX-3, VX-6 and VX-R even more accurate and rugged.How the CDS™ System Works The CDS System works by laser-inscribing your scope's elevation dial to match your load, velocity and conditions. Your scope will be in perfect synch with the way your rifle and load shoots, even for hand loads.Each CDS dial is unique, taking all practical ballistic and environmental factors into account

Quantum Optical System

Leupold mechanical and optical scientists, mechanical engineers and product line managers. have dedicated their design efforts over the last year to developing the optical system for Leupold’s newest generation of riflescopes, including the VX-1, VX-2, VX-R and VX-6. The Quantum Optical System™ is a leap forward and provides a new level of optical performance for hunters and shooters. Using the rugged foundation of the legendary Vari-X series and employing state-of-the-art optical and mechanical design software and manufacturing processes, this system delivers new levels of performance in every optical category. Lead free, ecologically friendly glass compositions are used throughout—the geometry of each lens is maximized through a combination of Ze-max® design software and evaluation usingLeupold’s Zygo® Interferometer to minimize wave front error andincrease resolution. The result is razor sharp imaging across the typical light conditions experienced on any hunt—from the bright daylight of varminting to the dawn and dusk hours when big whitetails are on the move. By repositioning optical elements, employing new coatings and importantly, leaving key, time-tested mechanical aspects of the Vari-X system untouched, significant performance gains have been achieved in many other areas as well. The Quantum Optical System has greatly enhanced light transmission (up to 92% in the VX-1 system and 94% in the VX-2 system), resolution and color fidelity—all while preserving the ease of use and nearly indestructible ruggedness that has been a hallmark of Leupold riflescopes for generations.

Xtended Twilight Lens System

Now your hunt can reach further into the twilight than ever before possible, with our exclusive new Xtended Twilight Lens System™. It goes a step further than even the Index Matched Lens System®, using Leupold’s® index matched glass with wavelength specific lens coatings designed to optimize the transmission of low-light wavelengths. When most scope manufacturers quote percentage of light transmission, they usually mean at 550 nm, the green wavelength where the human eye is most sensitive. The challenge is that in twilight conditions, green light disappears and blue/violet light takes over. Your eye is already handicapped when it comes to seeing the blue/violet spectrum, and if your scope is cutting too much of it out, soon you won’t be seeing anything. The Xtended Twilight Lens System places extra emphasis on matching coatings to glass indices to achieve the best possible transmission of the blue/violet spectrum, without sacrificing the color balanced light transmission across the visual spectrum of the Index Matched Lens System. When we combine that with superior computer-generated optical design, lead-free lenses of unsurpassed clarity and quality, and 100 years of manufacturing excellence, you have a scope that gives you the details of low-light scenes in greater definition and luminance than any other scope in the world.

DiamondCoat 2

Exterior lens surfaces are treated with DiamondCoat 2™, an ion-assist lens coating, for higher light transmission and the greatest level of abrasion resistance we’ve ever offered. DiamondCoat already exceeds military standards for hardness and durability. DiamondCoat 2 offers unsurpassed durability and will prove its worth in the wildest places on earth. DiamondCoat 2 has the additional advantage of assisting in light transmission, for greater brightness, clarity and contrast.

2nd Generation Argon/Krypton Waterproofing

While we still waterproof other optics with bone-dry nitrogen – technology pioneered by Leupold® – Select models feature our exclusive, proprietary Argon/Krypton gas blend. Its advantages are two fold: it nearly eliminates the effects of thermal shock, and the Argon/Krypton molecules are significantly larger than nitrogen molecules, reducing the diffusion of gases sealed inside your scope even more than our proven nitrogen technology already does. We pioneered riflescope waterproofing, and now with Argon/Krypton we’re exceeding the standards we set ourselves.

6:1 Zoom Ratio

A powerful 6:1 zoom ratio delivers crystal clear images from edge-to-edge throughout the entire magnification range. Many higher power scopes provide the best picture at each end of the zoom ratio, leaving the middle ranges weaker on clarity and resolution. The Leupold 6X erector system was engineered from the outset to provide consistently exceptional image quality across the entire visual field throughtout the entire zoom range. Twin Bias Spring Erector System features berylium/copper alloy leaf springs and 30% more holding force to withstand the most intense recoil and abuse.

Generous Eyebox

The generous eyebox makes it faster and easier to get your eye behind the riflescope and achieve a full, clear sight picture. Setting up for longer shots you'll appreciate the flexibility it affords, and in close up big game or dangerous game situations the quick target acquisition will be the difference maker. At high power, the longer eye relief and more generous eyebox gives you incredible head position latitude and an improved sight pictue that fills the eyepiece completely - putting you in better position to make the shot of a lifetime.
